  • Applications

    Harman (CAS 486-84-0) is primarily used as an intermediate for the synthesis of β-carboline derivatives and related pharmaceutical compounds; as a key building block in organic synthesis and medicinal chemistry research; as a reference standard for analytical methods (LC‑MS/GC) to identify and quantify β-carbolines in samples; in academic and biomedical research it is studied as a scaffold to explore biological activity and mechanism of action; and it is considered as a starting scaffold for materials chemistry applications, such as dye development and fluorescent probes.
